Patented Sept. 24, 1912.

Application filed February 14, 1910. Serial No. 543,724.

To all'whom it mag concern: I Be it known that I, J ULES H. Him, a c1t1- zen of the United States, residing at El Paso, in the countyof El Paso and State of Texas, have invented a certain new and useful Improvement in Processes of Producing Gas, 017' which the following is a specification.

This invention relates to improvements in 1 the process of making producer gas.

The object of the lnvention is to roduce a gas that is rich in carbon monoxld, by a continuous process, where the gas-forming combustible material is admitted at one part 1 of the gas generating chamber and producer gas is removed from another part of said chamber. The process also ,provides for reducing to carbon monoxid any carbon dioxid that may be formed. The process also pro- 2 vides for the proper reduction of the high temperature incident to the carrying out of the process.

The accompanying drawing illustrates one form of gas producer in which, or by means of which, the process may be carried out. The drawing Wlll serve only to clearly ascertain the process and is not in any sense to be understood as limiting the process to said apparatus, which is claimed in appli- 3 cation Serial No. 543,723 filed concurrently herewith.

The single figure of the drawing is a vertical section through the gas producer.

Referring to the drawing, the furnace 1 is of any suitable configuratlon and is shown as vertically disposed with its interior prefera'bly dome shaped at the top. This interior of the furnace is divided by a vertical wall 2 into the gas generating chamber 3 and the narrow passage 4: leading at the bottom to the water seal 6. An inlet pipe 7 leads to the bottom of the as generating chamber 3 and is upwardly directed. At its outer end a hopper 8 controlled by agate 9 near its bottom is in communication therewith, and a blowing means 10, such as a' blower or fan, is directed into the open end of the inlet pi e 7 adjacent the communication from the opper 8. A su plementary inlet pipe 15 communicates wlth the gas generating chamber 3 at a point slightly in advance of the pointat which the 1nlet pipe 7 communicates therewith, and is upwardly directed therein. At 5 its outer end this inlet pipe 15 is similarly provided wit-h a hopper 16 and with a blowing means 17. The Inlet pipes 7 and 15 are connected by a pipe 71 at points adjacent the hoppers 8, 16 to permit of secondary supply through the primary inlet.

steam pipe 11 is provided with valve controlled branch pipes 12, 13,14, and two of these branch pipes 12, 13, communicate with the gas generating chamber 3 at adjacent points slightly in advance of the point of communication of inlet pipe 15 with said gas generating chamber 3. These branch pipes 1.2, 13, are also slightly upwardly directed to said gas generating chamber 3. Branch pipe 14. passes upwardly through 7 wall 2 and at the highest point of the wall 2, communicates with the gas generating chamber 3. A supplementary valved gas starting inlet pipe 72 communicates with inlet pipe 7, said inlet pipe being forwardly 75 directed at the point of communication. A gas off-take pipe 5 communicates with' the passage 4 at 'a oint intermediate the gas generating chamber 3 and the water seal 6. This off-take where it is deslred to use the gas generated in the gas producer.

Operation: A carbonaceous material having been introduced into the hoppers 8, 16, the blowing means 10 is caused to operate, directing a blast of air axially into the outer end of inlet pipe 7 and past the discharge end of the hopper 8, the gate 9 having been adjusted to a suitable opening. Under these conditions, the ignition of the charge entering the other inlet pipe 7 having been effected in anysuitable manner, the gas forming combustible material consisting of an admlxture of finel divided carbonaceous material and air, wil be carried upwardly through the gas generating chamber 3 and around the to of wall 2 down through passage 4 toward the off-take pipe 5. During its pamage combustion will take place and the condition of completeness of such combustion will be determined by various ,conditions as to the extent of opening of the hopper gate 9 and the blowin means 10; also upon other extraneous con itions, such as the temperature of the as producer. Combustion having proceeded for a time,

the gas producer will become highly heated especially in the upper part of the gas generating chamberr 3, I In order to control the extent of the temperature rise, steam is pipe 5 passes to any point introduced through the Various branch pipes 12, 13, 14;, and these various points of introduction of the steam are designed to be at points of highest temperature. A chemical reaction takes place causing the disassociation of the elements of the steam or moisture into hydrogen and oxygen with a subsequent recomposition of these gases wholly or in part with a gas-forming combustible material burning in the gas generating chamber 3. Free hydrogen, methane or marsh gas, carbon monoxid, and possibly carbon dioxid, will be some or all of the resulting gases. I

In order to reduce any carbon dioxid that may be formed within the gas generating chamber 3, a supplemental introduction of gas-forming combustible material is made through the inlet pipe 15 by using the blowing means 17 in combination'wlth the gas cont-rolled hopper 16 having therein carbonaceous material. This carbonaceous material being introduced at a point of high temperature within the gas generating chamber 3, unites with the carbon dioxid gas, it any there be, reducing same to carbon monoxid. The air introduced through the blowing means 17 combines with other cars 'bonaceous material introduced thereby, the,

adjustment being such that the carbonaceous material is in excess.

The gas-forming combustible material of gas troduced either through t he main inlet pipe 7 orthe supplemental t'nlet pipe 15, may consist of liquid hydrogzarbon and air instead of carbonaceous material and air.

The ash-formed by the combustion, and any excess of solid material introduced into the producer, pass down through the passage 4 into the water seal 6 from whence they may be externally removed Without stopping the In the art of producing gas, introducing into the free space of a chamber an up wardly' directed blast of gas forming oombustible material, igniting-said blast, introducing into the same free space of said chamber a second upwardly directed bl ast forming combustible material, changing the direction of the flow of said combined blast, introducing moisture into said blastat the place of change and taking off from the changed flow the gas produced.

In testimony whereof, I afiix my signature in the presence of two witnesses.
